Today is Sunday. It's fine today. Jenny goes to the zoo with her mother. They can see many animals. There are tigers, lions, pandas, snakes and other animals. Look! The pandas are over there. They're from Sichuan, China. Look at the baby panda! It's climbing the tree. How cute it is!

    Next, they go to see the lions. The lions are so strong. Their mouths are too big. The tigers are next to them. They are from Asia. They are yellow and black. At last, Jenny and her mother go to see the monkeys. Some are climbing mountains, and some are eating bananas. The monkey is Jenny's favourite animal. It's so fun!

    Jenny sees a lot of animals at the zoo and she is so happy today!

    Tony Wheeler was born to travel. His father worked for an airline. For the first 16 years of his life, Tony and his family lived in many different countries.

    In the early 1970s, Tony met a young woman named Maureen. They soon married. Before getting jobs, Tony and Maureen wanted to travel. They took a year-long trip from England, through Asia, to Australia. On the trip, they visited places like Iran(伊朗), India, and so on.

    When Tony and Maureen arrived in Australia, people asked many questions about their trip. To answer these questions, Tony wrote a book called Across Asia on the Cheap. The book told people about different countries' weather, customs(风俗)，and places to visit. But unlike other travel books then, Tony Wheeler's book also talked about places most tourists did not go. He also wrote about unusual things to see and do. The book was very popular.

    Tony and Maureen started a company called Lonely Planet… They continued travelling. They wrote books for each place they visited. Today, 800 people work for Lonely Planet. The company has over 650 books. Tony Wheeler, the great traveller, still writes about travels to many places and will bring us more surprises.

Now about half of the world's population live in cities, but by 2050, cities will probably become even more crowded! All these people will need places to live, and energy to power their homes. This will put more pressure on the earth's resources. So we need to come up with more ways which are good for the environment to build houses, travel and make energy.

Covestro, a company in Germany, is working hard to make the future cities better. Rebecca, the head of the company, tells us the following exciting new ideas.

"As we all know, climate changes and pollution are the two biggest challenges facing the future. Right now, people use fossil fuel (化石燃料) too much for energy. That's not good for the environment. At Covestro, we set up Covestro's idea lab, scientists come together to solve problems here. "

"We've developed some new materials. Because of that, we are able to change wind turbines (风力发电机) and try to make them much bigger. Larger wind turbines mean that they can produce more energy. "

"We're working on lighter solar panels (太阳能电池板) so that one day we could provide power for our planes and cars with sunlight! Besides, we are also recycling carbon dioxide (CO2),which is the main cause of climate warming. By using CO2, we've already successfully made sports floors, car parts and even clothing. "

"In the future, materials will become lighter and more natural-looking. They'll become ‘smarter'. They'll need to be able to share information using special tiny machine, that's what Covestro is creating at the moment!"

Emma was nervous about the ceremony. She was the valedictorian(致告别辞者) for their class, and she was {#blank#}1{#/blank#}(worry) about speaking in front of such a large audience(观众). Emma wanted to practice her speech one more time with Julie.

But {#blank#}2{#/blank#} was Julie? Emma looked everywhere, but she couldn't find her. She called Julie's cell phone and sent her a few text {#blank#}3{#/blank#} (message), but Julie didn't answer. Emma didn't have much time, so she practiced her speech behind the curtains in the hall. Nobody saw her.

When it was time {#blank#}4{#/blank#}(line) up for the ceremony. Emma finally saw Julie." Where have you been?"

Emma asked Julie." I {#blank#}5{#/blank#}(call) you five times!"

" Sorry, I didn't hear my phone," replied Julie.

" Where have you been? I {#blank#}6{#/blank#}(look) for you, too."

"I was in the hall, practicing my speech," said Emma.

" Where? I didn't see you there," said Julie.

"I was behind the curtains," Emma said and laughed." That's why you couldn't find me!"

Julie laughed, too." Don't worry. You' ll do {#blank#}7{#/blank#} great job!" They took their seats. Emma sat in the front row. She was still {#blank#}8{#/blank#} (real) nervous. Then, someone handed her a piece{#blank#}9{#/blank#} paper. It was a note from Julie! It said," Good luck! You can do it!" Emma felt better and smiled.

" Sometimes paper is the {#blank#}10{#/blank#}(good) technology!" she thought.
